Over 700 languages are spoken in Indonesia and people are scattered across 6,000 islands varying in composition from rural fishing villages to highly metropolitan mega cities. Persecution is a reality for many believers in the most populous Muslim nation in the world. Although only 15% of the population follow Christ, the Indonesian church is experiencing profound unity as a result of the persecution, and mission organizations are growing in number. Indonesian believers also face a unique challenge as many of their neighbours are in geographical transition due to large-scale resettlement projects, migration, and forced relocation after natural disasters. However, the emergence of Indonesian (a form of  Malay) as the national language has allowed the Gospel to be communicated across ethnic and geographic borders as never before.
